UNITED STATES MYRON STANLEY CADWALLADER, OF CLEAN, YORK.

ADJUSTABLE BOOT ANDv SHOE LAST.

Application med February 21, 1922. serial No. 538,277.

To all 'whom t may concern.'

Be it known that Ii, MYRON S. CADWAL- LADER, a citizen of the United States, residing at Olean, in the county of Cattaraugus and State of New York, have invented certain new and useful Improvements in Adjustable Boot and Shoe Lasts, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to adjustable boot and shoe lasts, and the object of the invention is the construction of a simple and efficient last which is provided with means for efficiently stretching the toe portion of the boot or shoe.

Another object of the invention is the provision of simple and e'h'icient toe jaws adjustably mounted on arms of the last, whereby the extreme outer end of the toe of a boot or shoe can be stretched, or the whole toe portion stretched, just as the operator prefers.

With these and other objects in view, my invention comprises certain novel combinations, constructions and arrangements of parts as will be hereinafter described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a top, plan view of a device constructed in accordance with the present invention, showing the same in an extended position.

Figure 2 is a top, plan yview of the device, showing its arms and toe jaws in a closed position.

Figure 3 is a sectional view, taken 011 line 3 3, Fig. 1, and looking in the direction of the arrows. Y

Figure 4 is a sectional View, taken on line 4 4, Fig. 3, and` looking in the direction of the arrows.

Figure 5 is a sectional view, taken on line 5-5, Fig. 3, and looking in the direction of the arrows.

Referring to the drawings by numerals, 1 designates a frame which is provided with a longitudinally-extending slot 2, in which extends bar 3 that has teeth 4 formed in its upper face. Fastened to the outer end of bar 3 is heel jaw 5, which engages the heel portion of a slipper, or shoe, or boot. Formed upon the frame 1 is an apertured head 6, through which head 6 extends the threaded rod 7 on the Outer @11d Of rod 7' isa grip 8. Integral with the frame 1 and l 11. The enlarged portion 11 is positioned I between extension y9 and head 6,V and the rod 7 is threaded through the sleeve, Fig. 3, whereby the rod 7 maybe adjustedor moved back and forth, through the head'6, by turning the rod. frame 1, and in front of head' 6, is a pair of flanges 12, which are beveled, at 13, on their inner faces, soV as to allow'easy adjustment of the casing 14, between flanges 12. A' head 15 is formed on'the inner end of threaded rod 7, and this head 15 is positioned in socket 16 of the casing'14, whereby, when the rod 7 is threaded through sleeve 10, longitudinal adjustment of the casing 14 will be caused upon the frame 1. `A V-shaped block 17 is )fastened to the top of frame 1 contiguous toy theouter endsof anges 12, and U-shaped guides 16l are fastened at their outer ends to they top` of block 17, and at their inner of the outer ends of the flanges 12.r Outwardly-curved arms 19 are pivotally connected at their inner endsto the outer end of casino 14. These arms extend under the.

U-shaped guides 18,'and are adapted to engage the V-s'haped block 17.

A. pair of toe jaws. 2O are used, and each jaw 2O is similarly constructed. .Each jaw 20 comprisesa body having in itsv inner face an elongated sl'ot 21, this slot terminating in an upper groove 22yand a lower groove 23 (F ig. 5) in the body in which theends ot' pins 24 extend or slide. Pins 24 are placed inthe outer ends of the arms 19 by dropping the pins first through the apertures 25, of the jaws, then forcing the pins througn suitable apertures in the ends of the' arms 19. The advantage of having the outer ends of the arms 19 adjustably positioned in the slots 21 of the toe jaws, resides in the fact that if only the extreme outer end of the toe of the boot, or shoe, has-to be stretched, by forcing the arms to the extreme outer ends of slots 21, and then rotating the rod 7, the pressure will be brought to bear only upon the extreme outer ends of the toe jaws, whereas, by moving the outer ends of the arms 19 backward, and then operating the rod 7, the pressure will be exerted more upon the entire length of the toe;y sometimes Formed upon the ends to the top ,extension 9, bypiii 28. This latch QGfastens the bar lin an extended position, but by raising upward upon the Llatch, the bar 3 can be moved or forced inwardly upon frame l. By reason of' the adjustabilityof heel jaw 5 and bar Blupon theframe l, as well was the adjustability of arms 19 and` toe jaws 20, my device can be quickly applied to different-sized slippers, shoes, or boots,

W'hile I have `described the preferred eniloodiment of my invention, and have illustrated the same in the accompanying drawings, certain minor changes or alterations may appear toy one skilled in the art to which this invention relates, during the extensive manufacture of the saine and I, therefore, reserve the right to make such alterations or changes as shall fairly fall within the scope of the appended claims.

What I claim is:

l. In a device ol the class described, the combination of a trame provided with an apertured head vand with a .bifurcatedextension, a sleeve in said'bifurcated extension and provided at its inner end with yan enlarged portion positioned between the bifurcated extension and the head, va rod threaded through said sleeve and head, toe jaws, means connecting said toejaws to said rod, and a heel jaw adjustably .mounted upon said frame.

2. In a device of the class described, the combination of a frame provided with; flanges ,and a block, guides connected to said block and flanges, a casing slidably mounted between said flanges, arms between the block and flanges and under said guides and connected to said casing, toe jaws on said arms, means for adjusting the casing between said flanges, and a heel jaw attached to said frame.

macerie 3. In a device of theclass described, the

combination of a frame provided with a pair ot parallel flanges beveled at their outer ends, a substantially ill-shaped block secured to the frame contiguous to the outer ends of said flanges, guide means fastened to the block and to the flanges, a movable casing between said flanges, arms attached to said casing and positioned under said guide means, jaws on said arms, and a heel jaw attached to the rear end of said frame.

4. In adevice of the class described, the combination otl a frame provided witha pair of' flanges, a V -shaped block attached to the frame contiguous to the Vouter ends of .said flanges, U-shaped guides having their ends fastened to the block and the flanges, a socketed casing slidably mounted between the flanges,'arms under the guides and pivotallyT connected to the socketed casing, toe jaws carried by the outer ends of said arms, an `operating` rod seated at its inner end in said soclreted casing, and a heel awadjustably secured to the rear end of said frame.

5. 'In a device of the class described, the combination with a frame, of toe jaws posi tioned contignous to said frame andi provided in their inner faces with elongated slots` each toe jaw provided with upperand lower grooves opening upon the slot, each jaw provided with a pin-receiving aperture in its top and opening at vits innerend upon the upper groove` arms carried by the frame and extending through the slots, pins in the extreme outer ,ends of the arms and having their ends in the upper and lower grooves, and means carried ,by`Y the tramevand connected to the arms for ,adjustingythe same upon the frame. Y

6. In a device ofthe class described, the combination with arframe, .of toejaws .contiguous to said frame, each jaw provided with a slot and with grooves, each jaw provided with a pin-receiving aperture registering with the groovesv` arms -acljustably mounted upon said frame and extending into said slotand grooves, and pins inthe grooves and extending through -the arms.

In testimony whereof I hereunto affix' my signature.
